Description

【0001】
【産業上の利用分野】
本発明は、トングレールと床板摺動面に潤滑油を給油するための加圧式給油タンクに関するものである。
【0002】
【従来の技術】
トングレールの転轍動作時には、床面とトングレール摺動面の摩擦抵抗を軽減するために、摺動面に潤滑油を供給する必要がある。そのために潤滑油の給油装置と加圧装置とが用いられるが、潤滑油の給油装置については、本願出願人が、特願平10−132516号において開示している。
潤滑油の加圧装置は、鉄道道路の外側に給油タンクを設置し、配管にてトングレールの中間に設置した復動式油圧ポンプに給油するためのものである。
【0003】
この様に潤滑油をトングレールの所定の箇所に圧送するためには、外部の給油タンクより復動式油圧ポンプへ潤滑油を圧送する必要がある。
復動式油圧ポンプに潤滑油を供給するための潤滑油貯蔵タンクは、線路外側の列車の運行や保守点検に支障をきたさない位置に設置する。
【0004】
潤滑油は粘度が高いため復動式油圧ポンプに対して、潤滑油タンクより自然供給することについては問題がある。即ち、復動式油圧ポンプが粘度の高い潤滑油を自吸入するためには、ポンプのピストンに過大な荷重が掛かり、その為に転轍作業に支障をきたす危険性がある。
この様な危険性を回避するために、潤滑油の供給についてはタンクより給油する場合に、ある程度加圧して潤滑油を給油する必要がある。
本発明は、上述の如く復動式油圧ポンプに潤滑油を供給するための潤滑油の加圧式給油タンクである。
【0005】
摺動面を移動するトングレールと床面に潤滑油を供給する場合、線路の外側にある潤滑油の給油タンクから復動式油圧ポンプに潤滑油を加圧して供給する必要がある。従来、給油タンクに加圧する場合、潤滑油が減少すると油面が低下するので、油面の低下分に応じた錘を外部より鎖で供給する方法を採っているが、構造が複雑になり保守点検に支障をきたしている。
【0006】
潤滑油を圧送する方法として、加圧用のポンプを使用する方法も考えられるが、外部電源や保守点検等に問題があり、停電時や災害時には対応できない。
【0007】
【発明が解決しようとする課題】
本発明は上記情況に鑑みてなされたもので、上記従来技術におけるような欠点がなく、トングレールの転轍操作に支障を来たすことなく、しかも停電時や災害時においても、確実に復動式油圧ポンプに給油することができる加圧式給油タンクを提供することを課題とする。
【0008】
【課題を解決するための手段】
本発明は、トングレールと床板摺動面に潤滑油を給油するための給油タンクであって、前記タンクの上蓋を前記タンク内においてピストンとして機能するように前記タンク内に摺動可能に配置し、前記上蓋の自重で前記タンク内の潤滑油を加圧可能にしたことを特徴とする加圧式給油タンク、を以て上記課題を解決した。
【0009】
本発明の加圧式給油タンクは、潤滑油タンク自体を加圧タンクとして、潤滑油タンク本体が油圧シリンダーの役目をするようにしたもので、上蓋が油圧ピストンと加圧錘の役目をし、絶えず一定の圧力が潤滑油に掛かるようになる。
油圧ピストン兼用の上蓋には、潤滑油補給口兼空気抜き用のバルブを設け、上蓋を持ち上げるために蓋の中央にフック金具を取り付け、上方に簡易型の手巻きウインチを設け
【0010】
潤滑油を補給する場合は、空気抜きバルブを開放して、手巻きウインチで上蓋を持ち上げて、空気抜き用のホースを外して補給をする。
タンク内に潤滑油の補給が完了すれば、空気抜き用のホースを取り付け、ウインチを緩めて上蓋を降ろす
【0011】
【発明を実施するための最良の形態】
本発明の好ましい実施例について、添付図面に依拠して説明する。図1は、復動式油圧ポンプとトングレールを示し、図2は、本発明に係る加圧式給油タンクの正面図、図3はその縦断面図、そして、図4はその上面図である。
【0012】
本発明に係る加圧式給油タンクの説明の前に、潤滑油の加圧装置、及び、トングレールついて概略説明をしておく。
図1に示す如く、後述する加圧式給油タンクから圧送されてきた潤滑油は、給油側より、復動式油圧ポンプに供給される。
復動式油圧ポンプは、トングレールの枕木と枕木の間に固定する。復動式油圧ポンプ1は、構造上1個のピストンに対してピストンロッド2が両側に2本取り付けられている。
【0013】
ピストンロッド2の先端は、電気的に絶縁するために硬質絶縁樹脂3を取り付けるが、先端がトングレール4の内側に軽く接触する程度にピストンロッ2の長さを調整して取り付ける。
【0014】
トングレールが図1の矢印方向AからBへ、また、BからAへと転轍動作を行う際に、横移動のトルクを利用して復動の油圧ポンプ1を作動させる。
【0015】
復動式油圧ポンプ1のピストンがA側に移動する場合は、A側シリンダー内の潤滑油がピストンより押し出されて、A側の逆止弁5を経て、トングレールの側面に固定された油圧配管6を通して各枕木上の所定のトングレールと床板7の摺動面に供給される。
【0016】
復動式油圧ポンプ1のピストンがB側に移動する場合は、B側シリンダー内の潤滑油がピストンより押し出され、B側の逆止弁5を経て、トングレールの側面に固定された油圧配管6を通して各枕木上の所定のトングレール4と床板7の摺動面に供給される。
【0017】
上述の動作を繰り返すことにより、転轍作業が行われる場合に、その都度、適量の潤滑油をトングレールと床板の摺動面に供給することができる。
【0018】
図2乃至図4に示される本発明に係る加圧式給油タンク12は、上述の条件を満たすために潤滑油タンク本体を加圧タンクとし、例えば、内径250mmΦ、容積620リットルの潤滑油タンク本体が油圧シリンダーの役目をするようにタンクの内面に鏡面研磨が施される。
【0019】
上部の蓋14−1、14−2が油圧ピストンと加圧錘の役目をし、絶えず一定の圧力が潤滑油11に掛かるようにし、蓋の側面上下にピストンリングとしてOリング13取付けられて、潤滑油の洩れが防止される。
【0020】
加圧式給油タンク12から復動式油圧ポンプまでの距離は、最長で約20mあり、トングレールの稼働時に油圧ポンプのピストンに過大な荷重が掛からなくするためには、油圧ポンプの吸入側8で潤滑油の圧力が0.15kg/cm以上となることが必要である。それ以下の油圧では、転轍作業に支障をきたす危険性がある。
【0021】
油圧ポンプの吸入側8で潤滑油の油圧を0.15kg/cm以上確保するためには、14−1、14−2の重量を約70kgにする必要がある。
【0022】
本発明では、現地への搬入、設置時の作業性等を考慮してを2分割(14−1、14−2)し、現場にて組み立てることとした
油圧ピストン兼用の蓋14−1、14−2には、潤滑油補給口15と空気抜き用のバルブ20設け、蓋14−1、14−2を持ち上げるために蓋14−1の中央にフック金具17を取り付け、上部側面に簡易型の手巻きウインチ(荷重100kg)19を設けた。
【0023】
潤滑油を補給する場合は、空気抜きバルブ20を開放して、手巻きウインチ19を持ち上げて、空気抜き用のホース16を外して潤滑油補給口15より補給する。
タンク内に潤滑油の補給完了後、空気抜き用のホースを取り付け、ウインチ19を緩めて給油作業は完了する。
【0024】
【発明の効果】
上述の様にトングレール摺動面に潤滑油を供給する事に関して、本発明の加圧式給油タンクで、潤滑油に一定の圧力を加えて復動式油圧ポンプに供給することにより、トングレールの転轍操作に支障を来すことなく、安心して転轍操作が行われ、かつ、トングレール摺動面に潤滑油を給油する事ができる。なお、タンク12の下部潤滑油送出口に分配用コック21を設けることにより、本発明の加圧式給油タンク一台で複数のトングレールの油圧ポンプに潤滑油を供給する事ができる。

[Industrial application fields]
The present invention relates to a pressurized oil tank for supplying lubricating oil to a tongrel and a floor plate sliding surface.
[0002]
[Prior art]
During the rolling operation of the tongue rail, it is necessary to supply lubricating oil to the sliding surface in order to reduce the frictional resistance between the floor surface and the Tongrel sliding surface. For this purpose, a lubricating oil supply device and a pressurizing device are used. The lubricating oil supply device is disclosed in Japanese Patent Application No. 10-132516 by the present applicant.
The lubricating oil pressurizing apparatus is for installing a fuel tank on the outside of a railway road and supplying oil to a return hydraulic pump installed in the middle of the Tonglel by piping .
[0003]
In this way, in order to pump the lubricating oil to a predetermined portion of the Tongrel, it is necessary to pump the lubricating oil from the external oil supply tank to the return hydraulic pump.
A lubricating oil storage tank for supplying lubricating oil to the return hydraulic pump is installed at a position where it does not hinder train operation and maintenance inspection outside the track.
[0004]
Since the lubricating oil has a high viscosity, there is a problem with natural supply from the lubricating oil tank to the backward hydraulic pump. In other words, in order for the return hydraulic pump to suck the high-viscosity lubricating oil by itself, an excessive load is applied to the piston of the pump, and there is a risk of hindering the rolling operation.
In order to avoid such a danger, when supplying the lubricating oil from the tank, it is necessary to pressurize to some extent and supply the lubricating oil.
The present invention is a pressurized oil supply tank for lubricating oil for supplying lubricating oil to a return hydraulic pump as described above.

When supplying lubricating oil to the Tongrel moving on the sliding surface and the floor surface, it is necessary to pressurize and supply the lubricating oil from the lubricating oil supply tank outside the track to the return hydraulic pump. Conventionally, when pressurizing the oil tank, the oil level drops when the lubricating oil decreases, so a method has been adopted in which a weight corresponding to the oil level drop is supplied from the outside with a chain, but the structure becomes complicated and maintenance is required. The inspection is hindered.
[0006]
As a method of pumping the lubricating oil, a method using a pressurizing pump is also conceivable, but there are problems with the external power supply, maintenance and inspection, etc., and it cannot be handled during a power failure or disaster.
